Ep-37 what type of boating emergency causes the most fatalities?

The answer is capsizing. Most boating mortalities don't have anything to do with bad weather or dangerous sea conditions. They normally occur in smaller, open boats on inland waters during daylight hours when weather and visibility are good, the winds are light, and the water is calm. But in spite of these perfect conditions, passengers fall overboard and many boats capsize, causing over half of all boating fatalities.

Blood transfusions were rarely done and often fatal; they were outlawed until the nineteenth century.
